SEWER-TRAP.

SPECIFIGATION' forming part of Letters Patent No. 692,418, dated February 4, 1902. Application filed September 11, 1901. Serial No. 75,095. (No model.)

To au whom it may concern:

Be it known that I, HERMANN L. BEHRENs, a citizen of the United States, residing at St. Louis, State of Missouri, have invented certain new and useful Improvements iu Sewer- Traps, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

Myinvention has relation to improvements in sewer-traps; and it consists in the novel construction and arrangement of parts more fully set forth in the specification and pointed out in the claim.

In the drawings, Figure l is a perspective View of a conventional sink having my invention applied thereto. Fig. 2 is an elevation of the device, a section of the waste-pipe being broken away. Fig. 3 is an elevation of the lower section of the trap. Fig. t is a similar View of the upper section. Fig. 5 is a horizontal section on line 5 5 of Fig. 3; and Fig. 6 is a top plan of the trap, being a section on line 6 6 of Fig. 2.

The object of my invention is to construct a trap which shall take the place of the prevailing S-trap or gooseneck, my arrangement resulting in a cheaper and simpler construction, at the same time being more easily cleaned, since the interior thereof is readily accessible.

In detail the invention may be described as follows:

Referring to the drawings, S represents an ordinary sink, at the bottom of which is formed an opening for the reception of the body portion of a conical coupling section or ring 1, the latter being supported by a flange l', resting direct-ly on such bottom. Through the flange l are passed the screw-bolts 2, which serve not only to secure the ring 1 in place, but, passing, as they do, through the terminal ilange 3 of the waste-pipe 4, they serve to secure the latter to the bottom of the sink, a suitable washer 5 being interposed between the flange 3 and sink to increase the hold of the bolts. To the ring l is screwed the upper section 6 of the trap, the lower section 6 being coupled to the section 6. The lower end of the section 6 terminates in a cup 7, suspended a suitable distance below it, but whose upper edge is slightly above the lower end of said section 6', this arrangement causing the water lling the cup to rise above such lower end and form an effective water seal against any gases that might tend to work their way from the sewer to the sink. The cup 7 is suspended by the straps 8 or in any other suitable manner. The upper conical mouth of the upper section 6 of the trap is spanned by a perforated diaphragm or sieve 9.

It will be seen that my trap, being made sectional and in the form of a tube, may be readily taken apart and cleaned and yet has all the advantages of the ordinary S-trap, while possessing none of its disadvantages. It is apparent that the number of sections constituting the trap may be increased, if necessary.

Having described my invention, what I claim is A trap comprising a series of assembled conical tubular sections, a coupling-ring to which the upper section is secured, a flange forming a part of said ring, a waste-pipe having a flange located below the flange of the ring, bolts for securing the said anges to the opposite faces of the sink-bottom, a cup depending from the discharge end of the lower section of the trap, straps for securing said cup in position, the upper edge of the cup being located in a plane above the end of the said lower trap-section, substantially as set forth.

In testimony whereof` I affix my signature in presence of two witnesses.

HERMANN L. BEHRENS.
